Lift-and-slide doors from the GEALAN range enable large glazed areas with various construction options, as the system accommodates triple glazing of up to 52 mm in thickness. The HST system, based on the S 9000, meets all technical and visual requirements of next-generation sliding systems.

Acrylcolor is a technology specially reserved for this lift-and-slide door system. The PVC profile is permanently bonded to the coloured acrylic glass by extrusion. This creates an elegant, smooth surface that is resistant to environmental influences. The heat transfer coefficient in this system guarantees excellent thermal conditions indoors.
